Description
Mass Loaded Vinyl (MLV) is a high performance, flexible soundproofing barrier suitable for applications requiring a high level of soundproofing. With an ultra thin profile between 1mm to 4mm (approximately) and high acoustic performance of between Rw 26* & Rw30, MLV acoustic barriers are an excellent product to soundproof walls and ceiling spaces in residential homes & are particularly suitable for office partitions in commercial buildings. MLV is also commonly used in a wide variety of other applications such as soundproofing cars, boats, pump housings, machinery rooms or other industrial applications. MLV is dark grey or black in colour and Supplied in roll form, 1350mm wide by either 3 meters or 5 meter length.
Mass Loaded Vinyl Installation:
Mass Loaded Vinyl is very easy to cut and install. The product contains a fabric scrim with an embossed face increasing tear resistance whilst maintaining high flexibility. Walls / ceilings / under floors – the product should be tacked to studs / joists using tacks with large heads or incorporating a washer to minimize tear. Gluing is also beneficial. MLV can be glued to machinery housings, pump housings, boat or car structures to increase the mass and reduce sound transmission. Sheets should be butted up against each other, or overlapped and taped using a a strong industrial tape.
MLV Acoustic Noise Barriers Composition:
MLV is comprised of 3 elements. First, vinyl is employed to provide the product with a high level of flexibility for ease of use. Second, the Vinyl is impregnated with naturally occurring Barium Sulphate, a non toxic nature and high relative density substance. It is this high relative density (mass) that gives MLV such effective soundproofing capabilities. Finally, the vinyl and barium mixture is added to a reinforcing scrim to increase the products tensile strength.
Acoustic Ratings:
2 kg/m² — Rw 24
4 kg/m² — Rw 26
6 kg/m² — Rw 29
8 kg/m² — Rw 30
10 kg/m² — Rw 34
The Rw rating provides a single value that reflects how effectively a material reduces sound across the frequency range of 100 Hz to 3.15 kHz. This rating is based on standardised testing (AS/NZS 1276.1:1999) and independent test reports are available to verify performance.
